control limits and capabilities are within reason, and to ensure that the addition of a second shift isn’t causing issues to their process. To accomplish this, a data set was constructed. Ten bags were tested every hour during each of the two separate eight hour shifts. This continued for five days to give us 800 observations, 400 from each shift. The samples provided were analyzed for management using statistical process control methods, control charts for attributes, and capability analysis. This

It is important to prove that a process is proven capable before developing statistical control limits because it would be a waste of money if they went through the whole process just to find out it wasn’t capable. It would also be a waste of time and there is no business that

Process Improvement Plan Process Improvement Plan Process improvement helps with changes in a process to make, more efficient by eliminating wasted activities. The first step for improving time in getting prepared for work is deciding and establishing an outcome. This process will detail statistical controls that include control limits, seasonal factors, and confidence intervals based on the data. The data collected will show the timing of each step in getting ready for work. This
